Abstract

Hybrid “organic–inorganic” membranes are synthesized by growing a functionalized mesoporous “sol–gel”-derived SiO2 network into a hydrophobic fluorinated polymer. Processing guidelines are proposed to optimize the porosity at the macro-, meso- and micro-scales by templating the surface of the membrane through a modification of the thermal processing at 30–80 °C in air. Such a hierarchical design exploits the benefits of the facile water retention of the breath figure to produce membranes with high proton conductivity (50 mS cm−1 at 70 °C) under 100% relative humidity and develops the surface area and the interfacial area between the hydrophobic and hydrophilic domains.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
